Abstract
The invention relates to an improved brassiere lining material, which consists of thermal-plastic rubber and white oil which is 200 to 500 weight percent of the thermal-plastic rubber. The method for preparing the brassiere lining material mainly comprises: sending powdery or granular thermal-plastic rubber into a container for kneading until the temperature of the thermal-plastic rubber is between 30 and 40 DEG C; adding the white oil into the thermal-plastic rubber in the container, performing kneading until various materials are uniformly mixed, and making the white oil permeate into the thermal-plastic rubber; and performing thermal plasticization through an extruder, performing extrusion and granulation forming on a handpiece, and preparing the granular brassiere lining material. Theobtained material can effectively reduce the viscosity of a brassiere lining, greatly reduce the production cost (which can be reduced by at least 20 percent), and have the performance of the prior material.
Description
Technical field
The present invention relates to the composition of macromolecular compound, specifically, relate to a kind of improved be the bra liner material and preparation method thereof of base-material with the thermoplastic elastomer.
Background technology
Brassiere is the fashionable dress of chest, is used for protecting women's health, and makes the chest lines graceful more.Existing with the brassiere of moulding sponge as liner, after dressing, the women can increase its graceful bearing to a certain extent.But, this is that the brassiere of liner exists many deficiencies with the sponge, mainly show: the foam mat ventilation property is poor, have feeling of oppression and heat or cause the skin discomfort after dressing this brassiere, this situation is even more serious in summer, punching is to strengthen ventilation property on foam mat though some are also arranged, and the foam mat easy deformation after the punching is damaged; Because sponge elasticity is relatively poor, easy deformation is damaged, and therefore this brassiere can not be rubbed and wash, and this has influenced the sanitation and hygiene of brassiere; After the washing, contain in the foam mat, be difficult for drying than juicy; Sponge is easily aging, after this brassiere is changed clothes several times, foam mat aged problem can occur.
In order to address the above problem, the applicant in first to file patent of invention, the patent No. is 200410027046.9, name is called " a kind of bra liner material and preparation method thereof ", it is 5～10% talcum powder, lime carbonate or zinc oxide of above-mentioned thermoplastic elastomer that this bra liner material has adopted thermoplastic elastomer, weight, weight is that 12～25% oil of above-mentioned thermoplastic elastomer is a softening agent, and weight is that 1～3% ketoamine class anti-aging agent of above-mentioned thermoplastic elastomer is formed.
But the weak point of this bra liner material is: the material variety of employing is many, causes the production process more complicated, and the viscosity of product is too high, and the cost of product is also than higher.
Summary of the invention
For remedying the deficiencies in the prior art, the bra liner material that a kind of composition is simple more, viscosity is lower, cost is lower is provided, the present invention proposes a kind of improved bra liner material and preparation method thereof, and its technical scheme is as follows:
Each component and the content thereof of this improved bra liner material are:
Thermoplastic elastomer;
Weight is 200～500% white oil of above-mentioned thermoplastic elastomer.
In order relatively to effectively reduce the viscosity of bra liner material, above-mentioned white oil is selected at least a in No. 4, No. 5, No. 6, No. 7, No. 10, No. 15, No. 20, No. 68 white oils for use.
A kind of preferable scheme, above-mentioned white oil are selected at least a in No. 4, No. 5, No. 6, No. 7, No. 10, No. 15 white oils for use.
A kind of more excellent scheme, the weight of above-mentioned white oil are 300～400% of above-mentioned thermoplastic elastomer.
Above-mentioned thermoplastic elastomer can be thermoplastic elastomer SBS, thermoplastic elastomer SEBS, thermoplastic elastomer TPR, thermoplastic elastomer TPE (polyurethanes thermoplastic elastomer), thermoplastic natural rubber, melt processible thermoplastic elastomer or silicon rubber.
The preparation method of this improved bra liner material may further comprise the steps:
Step 1: powdery or granulous thermoplastic elastomer being sent in the container knead, is the 30-40 degree up to the temperature of thermoplastic elastomer;
Step 2: the thermoplastic elastomer in said vesse adds white oil, and it is even to each mixing of materials to knead, and white oil is infiltrated in the thermoplastic elastomer;
Step 3:, extrude then and, promptly make the granulous bra liner material in head pelletizing moulding by the forcing machine thermoplastication.
Described forcing machine can adopt single screw extrusion machine or twin screw extruder, and the feed section temperature of its screw rod is 150～180 ℃, and the compression section temperature of screw rod is 180 ℃～210 ℃, and the melt zone temperature of screw rod is 185 ℃～225 ℃.The temperature of screw rod feed section, compression section and melt zone increases successively.
The present invention is base-material with the thermoplastic elastomer, and after adding an amount of white oil successively and mixing, again through thermoplastication, the material that obtains has snappiness, thermoplasticity, good anti ageing property and higher flexibility (its shore hardness can hang down and reach-0025 degree).Make bra liner with this material, can effectively reduce the viscosity of bra liner, (production cost can reduce at least 20%) significantly reduces production costs, and the performance that can have original material (patent No. is 200410027046.9 the material that adopts in first to file in the background technology): can a plurality of breather holes be set easily on liner by Shooting Technique, improve the permeability of liner, because this material has snappiness, so the setting of breather hole can not cause the yielding damage of liner; With the soft and high resilience of bra liner that this material is made, comfortable especially when brassiere is worn; Because this material has good anti ageing property, therefore adopt the brassiere long service life of the liner of making by this material; Because the bra liner made from this material is soft and high resilience, so brassiere cleans conveniently, can be at will rubs with hand and washes or washing machine cleaning and can not cause the deformed damaged of liner, and the brassiere water content after the cleaning is few, dries easily; This material does not contain harmful material, and is safe in utilization; The bra liner thermal adaptation scope made from this material is big, is-50 ℃～80 ℃.
